Recent investigations of displaced clavicle fractures in adults have demonstrated a higher prevalence nonunion, symptomatic malunion, diminished functional outcome, and decreased strength with nonoperative treatment. Although these data led to increased surgical management fractures, little published information is available regarding the consequences malunion pediatric population. The purpose this investigation was assess pain, range motion, children treated nonoperatively.Clinical...
Background: Our aim was to assess whether the Lauge-Hansen (LH) and Muller AO classification systems for ankle fractures radiographically correlate with in vivo injuries based on observed mechanism of injury. Methods: Videos potential study candidates were reviewed YouTube.com . Individuals recruited participation if video could be classified by injury a high likelihood sustaining an fracture. Corresponding radiographs obtained. Injury using LH system as supination/external rotation (SER),...
In an intra-articular calcaneal fracture, the sustentaculum tali is generally thought to remain tightly bound talus by interosseous talocalcaneal ligaments, spring ligament, and deltoid providing a "constant" fragment that remains anatomically aligned. The extensile lateral approach commonly used for reduction based on this assumption, but because it provides only limited access medial aspect of calcaneus, indirect fracture required restore anatomic relationship these fragments sustentacular...
Measurement of the medial clear space (MCS) is commonly used to assess deltoid ligament competency and mortise stability when managing ankle fractures. Lacking knowledge true anatomic width measured, previous studies have been unable measure accuracy measurement. The purpose this study was determine MCS measurement error any influencing factors.Using 3 normal transtibial cadaver specimens, syndesmotic ligaments were transected widened affixed at a 6 mm (specimen 1) 4 2). left intact in...
In 1985, Silver et al. published a cadaver study which determined the relative order of strength muscles in calf. Muscle strength, is proportional to volume, was obtained by dissecting out individual muscles, weighing them, and then multiplying specific gravity. No similar studies have been performed using {\it vivo} measurements muscle volume.Ten normal subjects underwent 3-Tesla MRI's both lower extremities non-fat-saturated T2 SPACE sequences. The volume for each tracing contour on...
Considerable debate exists regarding how soft-tissue edema should influence timing of surgery for ankle and other lower extremity fractures. Assessment swelling is subjective, varies among surgeons. However, one the few modifiable factors in fracture care. Ultrasonography can objectively measure help determine optimal timing. The purposes this study were to whether objective measures swelling, surgery, patient-specific risk correlated with wound complications try create a prediction model...
Background. Utilization of physician rating websites continues to expand. There is limited information on how these function and influence patient perception physicians’ practices. No study our knowledge has investigated online ratings comments orthopaedic foot ankle surgeons. We identified factors impacting for this subset Methods. 210 surgeons were selected from the American Orthopaedic Foot Ankle Society (AOFAS) website. Demographic information, ratings, reviewed 3 most visited public...
Background. Bohler’s angle (BA) is the most commonly utilized radiographic measurement in study of calcaneus fractures and has been shown to be prognostic nature. Therefore, it critical that BA accurate as both therapeutic information relies on it. Oblique lateral radiographs can a cause error measurements. However, effects X-ray beam obliquity have not established literature. The purpose this was determine understand beam’s BA. Methods. A cadaver specimen imaged using C-arm obtain perfect...
The American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Scoring System (AOFAS-AH) has not been validated significant risk for researcher bias, given that 40 out of 100 points are assessed by study staff subjectively. purpose this is to evaluate its recent use in the orthopaedic literature determine percentage previously published studies which conclusions would be changed if AOFAS-AH scores were artificially altered, representing effect a systematic bias.Articles from January 2012...
Background: Patients with calcaneus fractures often exhibit settling of the posterior facet a corresponding decrease in Bohler’s angle (BA) following either operative or nonoperative treatment. Both injury BA and postoperative have been shown to be prognostic for outcomes; however, demographic surgeon-specific factors that may contribute not critically examined literature. The purpose this study was identify these causative factors. Methods: 234 patients intra-articular were analyzed. All...
Background: Classification of fifth metatarsal base fractures has been a source confusion since originally described by Jones in 1902. Zone classifications have but never evaluated for reliability. The most recent classification, metaphyseal vs meta-diaphyseal, may be unknown to many surgeons. purpose this study was evaluate reliability American Orthopaedic Foot & Ankle Society (AOFAS) members classifying and current management these fractures. Methods: A survey emailed AOFAS including...
Free tissue transfer is commonly required for reconstruction of distal third lower extremity injuries. Injuries involving the dorsal surface foot require thin pliable flaps. Musculocutaneous flaps are often too bulky to accommodate shoewear. Fasciocutaneous flaps, while an improvement, need secondary contouring procedures. The modified radial forearm fascial flap (MRFFF) may offer alternative.Twelve patients with wounds were reconstructed MRFFF + split thickness skin graft. modification in...
